Great job! You could consider covering any portion of the intercooler that faces a hot (engine) surface with heat reflective foil tape, just be sure to get the good stuff (4-5% reflectance, not the cheap 50% reflective stuff that blingers use... Here's a silver one: coastfab.com/heat-reflective-tape.html). You might want to wrap the aluminum portions of your tubing with the same, otherwise they'll pick up a ton of heat. Also is that a atmospheric BOV? If so shouldn't you really be running a recirculating BPV?
Cheers!
